(No modelli To @ZZ whom t may concern:

Be it known that I, EVERETT L. LAKE, a citizen of the United States,residing at the city of Syracuse, in the county of Onondaga and State ofNew York, have invented a new and useful Improvement in Brecch-LoadingFire-Arms, ot' which the following is a specifieation.

My invention relates to `improvements in hammerless breech-loading iii'e-arms; and the objects of my improvement are, first, to provide forcompensating the wear of the several parts; second to reduce the strainupon the .parts to the minimum in the opening ofthe gun; third, to use aplunger which shall strike the center of the cap in a line straight withthe `bore of the barrels, and, fourth, to discharge both barrels withone trigger. I attain these objects by the mechanism illustrated in theaccompanying drawings, in which- Figure l is a sectional view of thatportion of the gun to which my invention relates. Fig. 2 a top plan viewofthe foreend piece, with the loop-spring. Fi 3 is a view of the breechend of the barrels, with the inortise for the locking-bolt and for thecombined ejector and check-lever. Fig. 4 is a back end view of theplungers, plunger springs and arms, sears, and combined lscar andtrigger, hangers, ratchet, and star-wheel. Fig. 5 is a top plan view ofFig. 4, the dotted lines indicating the invisible parts. Fig. 6 is abottom plan view ot' the frame and lug; and Fig. 7 is a view of the backend of the frame, plunger and arm, and plunger-spring. Figs. 8, 9, andl() are additional views, showing in full lines the connection of theplungers with the sears, cooking-lever, and spring.

' Similar letters refer to similar parts tl1rough out the several views.

A represents the fore-end piece, in which there is a haltcircle, a, atone end, and near the other the niortise af, and riveted to the metalwhich forms the basis of the fore-end piece is the loop-spring b, whichspring is secured and held fast at both ends, and the loop extends intothe'niortise. (See Fig. 2.)

B represents the barrels, b the arm extending below the barrels, and bthe arnrpit.

C is the hinge pin or bolt with slot in the head, and the head istapered from the outsideto the socket or hingepin hole. .It is thenstraight; but after entering the frame beyond the socket or hinge-pinhole it is threaded and screws into a tapering nut. (See Fig. 6.)

D D represent the lug; c c c, the horizontal splits in the lug. d d arecompensating or grip screws passing up into the lug and across thesplits c and c.

E is the bridge in the frame; c, the compensating or grip screw passingthrough the frame and across the vertical split 'v in the frame 5 f, ascrew passing through that part of the lug which is over the bridge intoa slot, f, in the extractor; F, the extractor, and f the extractorsteadypin; H, a mortise for the locking-bolt; I, the combined ejectorand check-lever, fastened or hinged to the lug by a pin through theelbow, the lug being cut out to receive the lever operating theextractor and stopping the barrels when the gun is opened; i?, a springfastened to the lug for holding the lever in position; i', a shoulder onthe lug which stops the lever, and upon which the check-lever is pushedby the end thereof coming in contact with hook T in the frame, whichoperation moves the tail end or ejector back or ont, pushing theextractor, which draws or throws out the broken shell positively withoutstraining the hinge-joint, and stops the barrels from dropping down toofar.

K is a mortise in' the frame k to allow the operation of the check-leverin opening the gun; L, a lockingbolt, with mortise Z and spiral springl', N, a lever with hook n on the head to hold the lever from droppingdown when the fore-end is moved backward, freeing the inortise u fromthe pin p; M, a plunger with mortise m for receiving the free end of theplunger-spring; o, a notch or hook for receiving the sear when theplunger is cocked; O, the bent plungerspring with arm o below the centerand extending forward and coming in contact with the frame in front,stopping the spring at that point, while the free end whips orvibratesforward, carrying the plunger forward, so as to explodethe cap,and then vibrates backward, drawing back the plunger, (see Fig. 7 thefoot or stein ofthe spring entering hole o, drilled thereforin theframe, and fastened therein.

Pis an arm of the plunger to engage the le- IOO ver N, and the lever,`wh en drawn back, moves the plunger back till the nose of sear rengages the hook o and the plunger is cocked. The lever, when released,drops back to its point of rest upon p.

Sears o and r', the latter being broken off, as shown in Fig. l, arefastened or hinged to the tang T, the tail end of i' connecting with thestar-wheel S, while a" is combined with the trigger R. y

r is a spring fastened to the tang, the free end pressing against thetrigger, and throws the nose of the scar up so as to engage the notch inthe plunger when drawn back.

s is a pawl or dog fastened to the lever, and operates the ratchet-wheelu, and revolves bot-h ratchet and star wheell when the trigger is gpulled back, and by the pulling of the trigger the left barrel isdischarged, the star-wheel revolving so that sear o rests at the pointX, and the second pulling of the trigger revolves the star-wheel, whichthrows up the tail of sear r, disengaging the nose from notch o and theright barrel is discharged,

the sear o" not interfering with the movementr of the trigger.

t t are hangers from the tang supporting the axle s of the ratchet andstar wheel, (sce Fig. 4,) and s is the guard.

The fore-end piece A is secured to the gun by means of the half-circlea, inclosing the end of the frame, and the loop-spring b, fitting intothe arm-pit b. This piece is removed from the barrels by taking hold ofthe extreme forward end with the fingers and pulling away from thebarrels, the loop-spring flattening out with the pressure sufficientlytherefor. The loop-spring by its elasticity automatically compensatesfor the wear upon the halfcircle a in the opening of the gun. By meansof the hinge pin or bolt C, made as described, and the screws e, and thevertical split U in the bridge ofthe frame, I compensate for the lateralwear of the obvious parts. To compensate for the longitudinal wear ofthe lug upon the bridge and hinge pin or bolt, I provide the horizontalsplits c c c in the lug, and with the operating or grip screws d d closeup these splits, and thus the wear is taken up.

To operate the extractor and. stop the barrels from dropping too far andsave the parts of the gun from unnecessary strain, I have combined theejector with a checkllever in the manner shownin Fig. l, so that inunlocking the barrels, when the head of the lever comes in contact withthe hook J in the frame, the tail Yend of the lever then pushes theextractor back, which throws out the shell until the lever is stopped byand rests upon the shoulder t" of the lug, when the further opening isstopped, as indicated by the dotted lines. The mortise H in the barrelsreceives the lockingbolt L, and this bolt is withdrawn from the mortiseby a forward pressure upon the end of the leverNextendingdownwithinthetrigger-guard. The mortise fn in the lever Nallows the lever to be moved back free from the pin p, the

hook n on the headholding the lever from dropping down, and by drawingback this lever, it striking the arm l? ofthe plunger, moves the plungerback till the sears r r catch the notches o in the plungers and cockthem, the lever falling forward to its position of rest upon the pin p.'Ihe spring. O has a foot or stem to en ter the hole o', drilled in theframe,

(see Fig. 7 and is there fastened, the free end being in the mortise mof the plunger M, and when y the trigger is pulled the power of thespring carries the plunger forward, and by the whip or vibration of thefree end of the spring explodes the cap after the spring is stopped bythe arm o, and then withdraws the plunger within the frame. The plungerM moves in a straight line-with the bore of the barrels, and is providedwith the. mortise m` for the free end of the plunger-spring to enter,and the notch o for the sear to catch and cock the plunger.`

It is obvious that, having my cooking-lever and trigger inside of theguard, and the gun being without hammers, there is not even thepossibility of an accidental discharge; that, having a single trigger,the wrong one can never be pulled; that, the ejector acting directlyagainst the head of the extractor and the strain thereon, the extractorcannot slip by or off the shell 5 that there is a large gain in theleverage of the ejector and check-hook by placing them in the rear ofthe lug; that the end of the locking-bolt being wedging, thecooking-lever, having the power ofthe plunger- 'springs against it,locks the barrels tighter,the

spring in the rear of the bolt securing the gain; that the lock isdispensed with; that the vibrating spring communicates power to theplunger over all the space it passes, and hence the plunger strikes thecap a positive blow, certain to explode the cap; that the device whichstops the barrels when gun is opened reduces the strain upon the partsto the minimum.

I am aware of the several devices for compensating the wear of theseveral parts and for opening and closing, and for dispensing withhammers, and especially of my previous application, Serial N o. 58,766,and hence What I claim is- 1.. The combination of the lever N, with freeend within the trigger-'guard and power end in locking-bolt, having hooka, mortise a', with the locking-bolt L, provided with mortise Z, pin p,the lever N being adapted to swing upon either pin p or hook a, plungerM, provided with arm I), extending in the path of lever N when saidlever N is pulled backward', and notch o to receive scar r to unlock thebarrels or cock the plungers, as shown, and for the purposes specified.

6. In hainmerless guns, the vibrating spring O, having the arm o forstopping the spring at the point where the arm is attached,when the armstrikes the back end of the frame infront thereof as the plungeris/discharged,whilethe free end ofthe spring carries the plungeizmovingin a straight line forward to explode the cap, and then draws theplunger back to a position at rest, the front end of the plunger-beingWithin the frame, in combination with the plunger M, as shown, and forthe purposes specified.

7. The single trigger R, combined with the sear r', and provided withthe position-spring r and pawl or dog s', connecting with the star-Wheel S, provided With a ratchet-wheel, n, arranged to operate the searr and release the right-hand plunger M to discharge the right handbarrel without discharging the left-hand barrel, or vice versa, asshoivn,and for the purposes specified.

8. Spring O, having the arm o, in combination with the frame 7c, againstwhich the arm 0 strikes,and thereby stops the forward movement of thespring at the point where the arm is attached, plunger M, having mortisem to receive the free end of spring, notch dto receive the scar r', andarm P to engage the lever, lever N, and the discharging mechanismdescribed, to render the spring vibrating, as shown, and for thepurposes specied.
